Benefits of technology

[0048] By applying the present invention, a network device is become more QoS aware. The number of transmission permit required serving QoS streams are reduced. Contending of Wireless Medium is more scheduled and thus reducing the number of contention or collision as the wireless medium is shared by plural number of wireless station within a wireless network administered by a central controller. For a uninterrupted data stream transmission, the present invention allow contention based wireless med

Abstract

The present invention provides a method for transmitting data stream via wireless medium for contention based medium access across a wireless network having a plurality of stations and an access point communicating to the stations via wireless medium. The method includes: (i) transmitting data stream from the station according to prescheduled wireless medium occupancy reservation for the station within only prescheduled medium occupancy period of a selective contention period; (ii) performing a contention between the stations for wireless medium occupancy for a contention successful station to transmit data stream within only contention medium occupancy period of the selective contention period; (iii) transmitting data stream from the contention successful station after the contention; and (iv) prescheduling a wireless medium occupancy reservation for the contention successful station to transmit within a prescheduled medium occupancy period of next selective contention period.

Description

TECHNICAL FIELD [0001] This invention is to equip a network device with Quality of Service (QoS) awareness system process to serve traffic streams in a coordinated manner. This invention also increases QoS awareness and throughput efficiency of traffic streams transmission by coordinating stream transmission and reduce the number of collision for contention based medium access mechanism. BACKGROUND ART [0002] In prior art, the timing to obtain transmission permit for stream transmission that is not being coordinated are not base on the stream requirement. It will try to request for transmission permit without any other further consideration if the queue is not empty. Furthermore, the permit is granted based on priority as described in Draft, Supplement to International Standard ISO / IEC 8802-11: 1999: ANSI / IEEE Std 802.11, 1999 Edition—“Part 11: Wireless LAN Medium Access Control (MAC) and (PHY) Specifications (draft 3.0) and some random periods as described in International Standard...
